Summary translation

In the present diploma thesis, an experiment involving pea varieties was carried out under the conditions of organic farming in the pannonical climatic area. The experiment was conducted on the organically managed fields of the research farm of the University of Natural Resources and Applied Life Sciences Vienna. The aim of the experiment was to compare pure seed and mixtures of green and field pea varieties regarding their competitive ability against weeds and pests, their N2-storage capacity and N-dynamics in the soil, their feeding value and their economic efficiency. Generally, it can be concluded that in many aspects, field peas are equivalent or even better than the green peas. A limiting factor for the use of field peas as feed-stuff is their tannin content. Regarding the pea variety mixtures, these are not generally better than pure seeds. From this experiment, they have to be classified as being equivalent to the pure seeds.
